Hello,
Welcome to HTS. You have set aside a very prudent amount of funds to facilitate building an excellent HT.
For a Front Projector I would recommend the BenQ W7000. It has won a number of awards and is available for around $1800.
Here is a review:http://www.hometheater.com/content/benq-w7000-3d-dlp-projector-0

For a Screen I would go with a Stewart GreyHawk RS G3
For speakers I would recommend going to listen to some to establish what appeals to you. Unfortunately Newegg has sold out of some Klipsch floorstanding speakers that were literally available for $1000 off down to around $550 a pair and they still have the matching Center Channel and Surrounds. I would check out Audiogon for used speakers and do Zip Code search to ideally find something relatively close. Infinity, Paradigm, Klipsch, PSB, and Definitive Technology are just a few brands to look at for high value to performance speakers.
The best current deal on a speaker I can currently think of is the SVS SBS-02. We long recommended it here when it retailed for $300 and it is currently available for $149 a pair which is awesome. Using a Screen, you could order 3 pairs and use one for the Center Channel and have perfect timbre matching.

For a subwoofer, I would go with dual HSU Research VTF-2 MKiV given the size of the space. They sell for $559 plus shipping and are simply a fantastic value. Here is a link:http://www.hsuresearch.com/products/vtf-2mk4.html
For quite some time it was available for $519, but it has gone back to $559.
For an AVR, I would go with an Onkyo TX-NR809 especially as having a quality Video Processor takes on even more importance when using a front projector/screen setup. The HQV Vida is perhaps the best on the market and the 809 offers Audyssey MultEQ XT and THX Certification and Post Processing. It is a steal at $599 as it retailed for $1100.

That just leaves cabling. Go to Monoprice and save a fortune. The SVS's are quite good, but do check out what is available on the used market.
Best,
